13 Claims. (Cl. 132-41) This invention relates to a hair curler and pertains more specifically to a curler having a winding member which is adjustable in diameter.

In the permanent waving of hair, the customary procedure is to wind the hair upon the winding member of a hair curler for treatment with a permanent waving agent. The diameter of the winding member which is selected (hence the diameter of the wound hair tress) will depend upon the nature of the hair being waved, its previous history (i.e., whether it has previously been waved, bleached,

etc.), the location of the particular hair tress upon the head, and the tightness of the wave desired. For these reasons, it has hitherto been necessary to supply curlers in a number of different sizes.

One object of the present invention is to provide a hair curler having a winding member which is adjustable in size, the diameter of which may be adjusted at will over a considerable range and which maintains the selected diameter until it is intentionally changed.

Another object is to provide a hair curler having a winding member of open or foraminous construction permitting ready circulation of a waving agent throughout the wound hair tress during the waving process and of air during the neutralization and drying steps and which is adjustable at will to any one of a number of selected diameters without variation in length.

Still another object is to provide a hair curler having a winding member of simple and inexpensive construction which is adjustable in diameter and which is adapted to be used in styling or setting hair as well as in waving.

A further object is to provide a hair curler of the type described which includes a hasp having a free end which is releasably engageable with the winding member at a variety of positions and which overlies a tress of hair wound on the winding member to maintain the curler in the desired position in the hair.

Still another object is to provide a hair curler of the type described in which the hasp and the winding member are of unitary construction and are molded of resilient, flexible, synthetic plastic material.

Other and further objects will be apparent from the drawing and from the description which follows.

As appears from the drawing, the embodiment of the invention there illustrated comprises a winding member consisting of a flexible grid or reticulate sheet 10 formed of intersecting longitudinal ribs 12, 12 and transverse ribs 14, 14. These ribs preferably consist of a flexible, resilient, synthetic plastic material such as polyethylene, plasticized polyvinyl chloride, or similar material which is inert to the ingredients of a hair waving, setting or treating lotion. Disposed along one longitudinal margin of the grid or reticulate sheet 10 are a plurality of hooks 16, 16 which are preferably molded of the same synthetic plastic material integrally with grid 10 and are of such a size as to be engageable with any of longitudinal ribs 12, 12 when the sheet is rolled upon itself. An elongated hasp member 18 is provided, one end of which is secured to one lateral margin of the grid adjacent a corner of the grid remote from books 16, 16 as shown in Fig. 1. The hasp member is preferably molded of synthetic plastic material and may be integral with grid 10. The free end of hasp member 18 carries a hook 20 which is desired configuration, either straight or curved.

Although the grid or reticulate sheet 10 is shown in the embodiment of Fig. 1 as being of generally rectangularconfiguration with the ribs 12, 14 intersecting each other' at right angles to form rectangular openings, it will be understood that the sheet may be of triangular or other shape if desired, and that the ribs may intersect each other at varying angles. In addition, transverse ribs 14,. 14 may be made smaller in cross section than longitudi nal ribs 12, 12 to facilitate rolling sheet 10 as shown in. Figs. 3 and 4.

In use of the device, the reticulate sheet 10 is rolled. spirally upon itself, as shown in Figs. 3 and 4, to form. a winding member which is generally cylindrical in shapeand which is of any desired diameter. Hooks 16, 16 arethen engaged with the appropriate longitudinal rib 12 of the underlying layer of the spirally wound roll to maintain the winding member in its desired position. The: curler is then adapted to be employed in the usual mannerby winding a hair tress upon it, whereupon the hook 20* of hasp member 18 may be engaged with the appropriate; transverse rib 14 to maintain the tress in wound condi-- tion and hold the curler in the hair in the desired posi tion with hasp member 18 overlying the wound tress.

Another embodiment of the invention is shown in. Figs. 7 and 8 of the drawing in which hooks 16, 16 are: replaced by resilient stud fastening elements 30, 30 which! frictionally engage in the interstices between adjacentpairs of ribs 14, 14, 16, 16 to hold the sheet in spirally rolled configuration. this embodiment is secured adjacent to but inwardly spaced from the longitudinal margin remote from fasten ing elements 30, 30, and supplemental ribs 34, 34 are provided in the narrow zone between the hasp member and the adjacent longitudinal margin to provide additional stifiness in this zone and to facilitate gripping and rolling" of the sheet upon this zone as a core.

In the embodiment shown in Fig. 9, a large number opposite face of the sheet from that on which fastening:

elements 30, 30 are disposed. Accordingly, when the In addition, hasp member 32 of reticulate sheet is rolled spirally upon itself in the manner indicated in Figs. 3, 4 and 8, projections 40, 40 extend radially outwardly, entering into the hair tress as it is wound on the curler and holding the hair fibers more securely in the desired aligned relation.

It will be appreciated that the construction of the present invention makes it possible to select any one of a number of different diameters for the hair-winding memher and to adjust the diameter of the winding member at will without varying the length thereof. Furthermore, the unitary, one-piece, integral construction of winding member and hasp ensures an inexpensive construction.

Although specific embodiments of the invention have been herein described, it will be understood that the invention is not limited thereto, but includes any of the obvious variations and modifications within the spirit and scope of the appended claims.
